Especially at the design stage. Changing engines to the big ass CFM LEAP 1 caused a major design issue.
To keep ground clearance, they moved the Nacelle forward , changing the CG of the aircraft, making it in effect an new plane for pilots, not just a new 737.
Also the top of the nacelle is level or even slightly above the wing, causes lift and drag issues on the wing itself.
If Boeing's CEO used his damn engineering degree he would have questioned this.
But he was using his CEO quarterly profit hat.

Actually, the current Boeing CEO has an engineering degree. The one at the time the 737 Max came out was BA Yale, MBA Harvard. Worked at Procter and Gamble on brand management.

You’re quoting internet blab.

Any pilot can safely fly the plane’s design without MCAS. You have no idea what you’re talking about here. This has been discussed AT-LENGTH in other threads.

No, as a retiresd Pratt and Whitney Sr Engineer, from the experimental airfoil group, who worked on large fan engines, up ro 112” dia, and the engines in PW5000, ie. the F119 engine in the F22, I have some personal knowledge of how engines affect cg, and how important weight distribution and nacelle shape are to air
f;ow over the wing. Also a simple inclinometer stops , ie mercury switches set at certain angles, could have easily alerted the controller that the plan had over reached allowed wing angles. It’s been done before. But it’s so analog.
